René Descartes ( day-KART, also DAY-kart; French: [ʁəne dekaʁt] ; 31 March 1596 – 11 February 1650) was a French polymath, active across philosophy, including metaphysics, epistemology, ethics, and the philosophy of science; theology; mathematics, in which he connected the previously separate fields of geometry and algebra into analytic geometry; science, including physics, optics, mechanics, cos De… According to Descartes, two substances are really distinct when each of them can exist apart from the other. Thus, Descartes reasoned that God is distinct from humans, and the body and mind of a human are also distinct from one another. He argued that the great differences between body (an extended thing) and mind (an un-extended, immaterial thing) make the two ontologically distinct. According to Descartes's indivisibility argument, the mind is utterly indivisible: because "when I consider the mind, or myself in so far as I am merely a thinking thing, I am unable to distinguish any part within myself; I understand myself to be something quite single and complete." Moreover, in The Meditations, Descartes discusses a piece of wax and exposes the single most characteristic doctrine of Cartesian dualism: that the universe contained two radically different kinds of substances—the mind or soul defined as thinking, and the body defined as matter and unthinking. The Aristotelian philosophy of Descartes's day held that the universe was inherently purposeful or teleological. Everything that happened, be it the motion of the stars or the growth of a tree, was supposedly explainable by a certain purpose, goal or end that worked its way out within nature. Aristotle called this the "final cause", and these final causes were indispensable for explaining the ways nature operated. Descartes's theory of dualism supports the distinction between traditional Aristotelian science and the new science of Kepler and Galileo, which denied the role of a divine power and "final causes" in its attempts to explain nature. Descartes's dualism provided the philosophical rationale for the latter by expelling the final cause from the physical universe (or res extensa) in favor of the mind (or res cogitans). Therefore, while Cartesian dualism paved the way for modern physics, it also held the door open for religious beliefs about the immortality of the soul. Descartes's dualism of mind and matter implied a concept of human beings. A human was, according to Descartes, a composite entity of mind and body. Descartes gave priority to the mind and argued that the mind could exist without the body,…

Thus Descartes maintained the absolute dualism of the res cogitans and the res extensa. Spinoza realized the flaw in the division and preferred to postulate behind mind and matter a single substance (unica substantia) while Leibnitz explained the universe as a harmony of spiritual or semispiritual principles. Kant practically abandons the problem. He never really establishes a relation between pure reason and things-in-themselves (Dinge an sich), but rather seeks refuge in a dualism within consciousness, the transcendental and the empirical. Since Kant there are, therefore, two streams of dualism, dealing, one with the radical problem of the relation between mind and matter, the other with the relation between the pure rational and the empirical elements within consciousness. To the first problem there is one obvious and conclusive answer, namely that matter in itself is inherently unthinkable and comes within the vision of the mind only as an intellectual presentation.

Abstract In a recent article (1999b) I criticized Ryle’s failure, acknowledged in his Dilemmas (Ryle 1954), to develop an adequate account of the notion of a “category” in the following paragraph: Ryle’s failure to sharpen up the notion of “a category” is unfortunate for two reasons. Firstly, because he needs to rebut the claim made by Descartes and his followers that the distinction between the mental and the physical, between the res cogitans and the res extensa, is a distinction of category, using the term “category” in its Aristotelian sense in which a category is the kind of thing you end up with if you go on asking the question “And what kind of a thing is that?” and of which the category of substance (oucria) is the prime example. Secondly, because the distinction he himself draws be­ tween “disposition verbs,” “activity verbs” and “achievement verbs” corresponds to the· distinction between states of affairs of which dispositions are an instance and which persist unchanged over a period of time, processes which are extended over time with continuous change and instantaneous events (stops and starts) whereby one state or process ends and another begins, which occur at moments of time, but are not extended over time. Not only do these groupings have a much better claim to be de­ scribed as “categories” than do the mental and the physical, it is evident that the distinction between these three basic categories can be drawn on either side of the mental/physical divide.

Çağdaş zihin felsefesinde Kartezyen Düalizm genellikle Descartes’in zihnin maddi bir şey olmadığı tezine işaret eden bir terim olarak kabul edilmiştir. Kartezyen ontoloji yalnızca iki tür töze izin verdiğinden, insan da sonuçta tamamen iki bağımsız, yabancı tözün birleşiminden oluşan bir varlıktır. Onun bir parçası olan beden, mekanik dünyanın bir parçası olarak, bütünüyle maddi ve yayılımlı olan (res extensa) bir tözdür. Bu yüzden, insan bedeninin işleyişi yalnızca fiziksel ve mekanik terimlerle, yani hareket halindeki maddenin yasaları ile açıklanabilir. Oysa zihin bütünüyle maddi olmayan ve bu yüzden de uzamsız düşünen (res cogitans) bir tözdür. Böyle düalist zihin felsefesine ilişkin en belirgin sorun, onun, yani zihnin maddi olmayan bir şey olmasından kaynaklanır. Zihnin maddi bir şey olmadığı fikri ise kaçınılmaz olarak zihin ile beden arasındaki ‘birlik’ ve ‘etkileşim’ problemini de beraberinde getirmiştir. Bu makalenin amacı, düalist tezlerin aksine, zihin ile bedenin zorunlu ‘birliği’ve özelikle psikofiziksel etkileşimlerin doğasına ilişkin Kartezyen iddiaları eleştirel bir yaklaşımla ele alınıp değerlendirmektir

Wacana tentang ruang dan waktu merupakan isu yang selalu menjadi polemik di kalangan banyak filsuf dan ilmuwan hingga saat ini. Mereka mencoba merumuskan ruang dan waktu secara subyektif. Karena sejatinya keberadaan setiap makhluk tidak akan pernah lepas dari segala macam dikotomi yang ada baik secara spasial maupun non-spasial. Rene Descartes, salah satu filsuf rasionalisme, mengemukakan pandangannya tentang ruang dan waktu yang berangkat dari konsep substansi. Konsep substansi itu sendiri dimaknai sebagai sesuatu yang berdiri sendiri tanpa bantuan apapun. Tujuan dari penelitian ini adalah untuk memahami dengan baik sekaligus membuka cakrawala berpikir dalam mengetahui dan memaknai keberadaan setiap makhluk dan segala aktivitasnya yang ada baik secara spasial maupun non-spasial. Penulisan jurnal ilmiah ini menggunakan metodologi pendekatan kualitatif-deskriptif dengan menggunakan studi pustaka. Sumber bacaan yang digunakan kemudian dikaji berdasarkan hubungannya dengan kajian fenomena yang dibahas dalam kerangka filsafat. Descartes dengan pemikirannya yang cemerlang telah membangun konsep rasionalitas yang sangat mengagumkan, terlihat dalam adagiumnya yaitu Cogito Ergo Sum yang digunakannya sebagai metode dalam mencari kepastian tentang pengetahuan yang mutlak. Melalui adagiumnya, Descartes kemudian dirangsang untuk berpendapat tentang ruang dan waktu yang bertitik tolak dari substansi. Substansi ini kemudian dibagi menjadi dua sifat utama oleh Descartes yaitu (Res Cogitans) merupakan substansi jiwa yang memiliki sifat spiritual dan tidak eksis secara spasial. Sedangkan (Res Ekstensa) adalah zat materi yang memiliki sifat ekspansif, dan ada secara spasial, atau selalu membutuhkan ruang. Dari dua substansi inilah yang membuat ruang dan waktu ada dalam terang rasionalisme Descartes.

Res Cogitans e Res Extensa compõem os principais pilares da filosofia de René Descartes. O dualismo cartesiano e suas implicações de união substancial e ao mesmo tempo distinção entre corpo e alma provocam diferentes problemáticas no que se refere a compreensão desta que seria uma ideia “confusa e obscura” de René Descartes. A proposta deste trabalho é por meio da prova da existência da res cogitans e da res extensa traçar o caminho seguido por René Descartes ao estabelecer uma relação entre as duas substâncias, conferindo a elas diferentes atributos por meio dos quais são concebidas. Elementos fundamentais da filosofia racionalista de Descartes, como a dúvida com relação aos dados proveniente dos órgãos dos sentidos, ganham importância ao concebermos e provarmos a existência da alma e do corpo. Com o exemplo do piloto em seu navio, o filósofo francês, diferencia-se de Platão, não considerando o corpo um mero veículo da alma, mas estabelecendo uma relação estreita, como uma mistura de duas substâncias completas. No mais, conclui-se que a discussão acerca do dualismo cartesiano se trata de relacionar corpo e alma como um amalgama único, substâncias unidas, porém distintas que são tomados como a base de todo um sistema filosófico por constituir os seres humanos.

domain he called res cogitans (the realm of thought), in contrast to the domain of material things, which he called res extensa (the realm of extension) Consciousness is being aware of something internal to one's self, or of states or objects in one's external environment. It has been the topic of extensive explanations, analyses, and debate among philosophers, scientists, and theologians for millennia. There is no consensus on what exactly needs to be studied, or whether consciousness can be considered a scientific concept. In some explanations i Mental processes (such as consciousness) and physical processes (such as brain events) seem to be correlated, however the specific nature of the connection is unknown. The first influential philosopher to discuss this question specifically was Descartes, and the answer he gave is known as mind–body dualism. Descartes proposed that consciousness resides within an immaterial domain he called res cogitans (the realm of thought), in contrast to the domain of material things, which he called res extensa (the realm of extension). He suggested that the interaction between these two domains occurs inside the brain, perhaps in a small midline structure called the pineal gland. Although it is widely accepted that Descartes explained the problem cogently, few later philosophers have been happy with his solution, and his ideas about the pineal gland have especially been ridiculed. However, no alternative solution has gained general acceptance. Proposed solutions can be divided broadly into two categories: dualist solutions that maintain Descartes' rigid distinction between the realm of consciousness and the realm of matter but give different answers for how the two realms relate to each other; and monist solutions that maintain that there is really only one realm of being, of which consciousness and matter are both aspects. Each of these categories itself contains numerous variants. The two main types of dualism are substance dualism (which holds that the mind is formed of a distinct type of substance not governed by the laws of physics), and property dualism (which holds that the laws of physics are universally valid but cannot be used to explain the mind). The three main types of monism are physicalism (which holds that the mind is made out of matter), idealism (which holds that only thought or experience truly exists, and matter is merely an illusion), and neutral monism (which holds that both mind and matter are aspects of a distinct essence that is itself identical to neither of them). There are also, however, a large number of idiosyncratic theories that cannot cleanly be assigned to any of these schools of thought. Since the dawn of Newtonian science with its vision…
